Overview

You can join a Zoom meeting via teleconferencing/audio conferencing (using a traditional phone). This is useful when:

you do not have a microphone or speaker on your PC/Mac,

you do not have a smartphone (iOS or Android) while on the road, or

you cannot connect to a network for video and VoIP (computer audio)

Zoom has toll numbers available for many countries that are included with all plans. For audio plan subscribers, Zoom also has toll-free and additional toll numbers available. The dial-in numbers available are dependent on the host's audio subscription and settings.

After joining a Zoom meeting, you will be prompted to join the audio automatically. If this prompt does not appear or you close it, tap Join Audio in the meeting controls.

Tap Dial In.

Tap the arrow at the top to select the country you're calling from, if not selected by default.

Tap the phone icon next to the number you want to call.

Tap Call.

If prompted, allow Zoom to make and manage phone calls.

Return to your home screen and open Zoom again.

When you leave the meeting, you will have the option to Leave Meeting or Leave Meeting with Telephone Connected, to stay dialed into the meeting after leaving from the Zoom app.

Note: If you're on a Android device that can't make calls, follow the instructions for dialing in:

Dial one of the numbers provided.

Enter your meeting ID, followed by #.

Enter your participant ID, followed by #.

Tap Back after dialing in.

If you joined computer audio automatically, you can leave the computer audio and join by phone:

Tap More.

Tap Disconnect Audio.

Tap Join Audio and follow the instructions above.

Joining a meeting by phone only

Dial an in-country number. If you dial a toll number, your carrier rates will apply. You can find the numbers on your meeting invitation or a full list of international dial-in numbers at https://zoom.us/zoomconference.

You will be prompted to enter the meeting ID - the nine (9), ten (10), or eleven (11) digit ID provided to you by the host, followed by #.

If the meeting has not already started and join before host is not enabled, you will be prompted to enter the host key to start the meeting, or to press # to wait if you are participant.

You will be prompted to enter your unique participant ID. This only applies if you have joined on the computer or mobile device or are a panelist in a webinar. Press # to skip.

If you join by computer or mobile device later, you can enter the Participant ID to bind your phone and device session together and show your video when you speak on the phone. To enter your participant ID once you are in the meeting, enter #Participant ID# on your phone.

Phone controls for participants

The following commands can be entered via DTMF tones using your phone's dial pad while in a Zoom meeting:

*6 - Toggle mute/unmute

*9 - Raise hand

Entering the meeting password using your dial pad

If the meeting requires a password, a phone-specific numeric password will be generated. You can find this password in the invitation listed below the dial-in numbers and meeting ID.

Hosting phone-only meetings

You can join and start any Zoom meeting from your telephone and control the meeting with DTMF tones. To be recognized as the host, you will need to enter your host key, which you can find on your user profile

Note: If you enable join before host and join only from your telephone, you will not be recognized as the host and will not have host controls. If you need to host meetings from your phone with full host controls, do not enable join before host.

Considerations for joining by phone as the host

If you have scheduled the meeting from a basic account, the meeting will timeout after forty-minutes with a thirty minute warning notification, if two or more participants join or you do not bind your phone and computer/mobile device session with the participant ID.

If you would like the meeting to last for unlimited duration, the meeting will need to be scheduled by a Licensed user, on a Pro or above account.

The number of phones that can connect to a Zoom meeting or webinar is determined by account type and add-on assigned to the user account.

Licensed User: 100 Dial In Users

Licensed + Large Meeting 200: 200 Dial In Users

Licensed + Large Meeting 300: 300 Dial In Users

Licensed + Large Meeting 500: 500 Dial In Users
